The Lock Screen command mutes and disables all browser windows on a student’s device. Use it to redirect student attention or prevent access to content during a class session. The lock clears automatically when the session in which the student was locked ends. Any teacher with an active session can also unlock the student manually.
Lock Screen only disables browser windows. Applications running outside of the browser are not affected. If a locked student joins another session before the original session ends, the lock carries over to the new session.

Lock a Student’s Screen

Lock one student: Click the 3-dot menu on the student’s tile and select Lock student’s device. Lock multiple students:
  1. Check the boxes next to each student you want to lock.
  2. Click the Lock / Unlock device button.
  3. Enter a custom message to display on the locked screen. This step is optional.
  4. Click Lock devices on the confirmation dialog.
Click Lock devices on the confirmation dialog.

Unlock a Student’s Screen

Lock a Student's Screen
  1. Check the boxes next to each locked student.
  2. Click the Lock / Unlock device button.
  3. Click Unlock, then confirm by clicking Unlock devices.
  4. Confirm that the students’ tiles return to showing their active tabs.
A locked student’s tile always shows “You have locked this student’s screen” regardless of which teacher originally issued the lock. Any teacher in an active session with the student can unlock them.

Troubleshoot a Device That Stays Locked

If a student’s device does not unlock within 30 seconds:
  1. Restart the student’s device.
  2. Wait for the student to reconnect to the session.
  3. Issue the unlock command again.
If the student’s screen does not show “browsing disabled,” a different source may be blocking their browser. See the GoGuardian block page types article for more information.
